One of the most popular adult sex toys for gay men these days is the penis pump! The average male penis size with an erection is about six inches. Many men though are not happy with their natural penis size and thus seek methods to make their average penis into a larger cock. Although surgery exists, using a penis pump is much easier and less expensive to enhance penis size. The pump is placed around the base of the penis so that no air can get in. The man inserts his erect penis into the enlargement device and then pumps out the air which creates suction within the pump to stretch the penis to a larger size.
